ALUMINUM VALVE DISCOVERED INSTALLED IN CONTAINMENT

"While Unit 1 was in Mode 5, for the 15th refueling outage, an issue was identified with the valve material of an existing installed airlock hydraulic system valve. The valve was determined to have an aluminum body which is not suitable for safety related use in containment.

"The Unit 1 airlock hydraulic system penetrates the containment pressure boundary. The airlock hydraulic system achieves containment integrity by being a closed system under GDC-57. A loss of pressure boundary integrity would no longer meet General Design Criteria 57 (GDC-57) for a closed system.

"Aluminum is a restricted/limited material in containment because it is not compatible with accident conditions and has failures with multiple adverse effects. Due to this condition, the valve would potentially lose pressure integrity during a LOCA with containment spray actuation.

"Compensatory measures have been taken to prevent containment spray from affecting this valve and at this time, the airlock is operable.

"Luminant Power determined this issue to be reportable at 1545 [CDT] on 10/18 per 50.72(b)(3)(ii)(B) Comanche peak Unit 1 being in an unanalyzed condition that significantly degrades plant safety.

"The Unit 2 airlock is a different design and this condition does not apply to Unit 2."

This material was installed during original construction and discovered during a licensee self-assessment.

The licensee will notify the NRC Resident Inspector.
